You can find all the basic information about your hosting plan in one place. Navigate to the Websites section of hPanel and click on the Dashboard next to your website.
Once inside the Websites page/section, on the left sidebar, search for Hosting plan → Plan Details:
The Plan Details page contains the following:
Website Details — your domain name and website's IP address.
Nameservers — the current NS records on your domain as well as the Hostinger values. Make sure to check on how to point a domain to Hostinger if your domain is purchased elsewhere.
Server Details — the name and location of your server, and the option change its location.
FTP Details — information needed to connect to your account via FTP.
NOTE
The dashboard section on hPanel will not appear if you only have websites built with Hostinger Website Builder. To enable the dashboard section and its sidebar options, add another website that's not built using the Website Builder.
